RESUMO

BACKGROUND: The SARS-CoV-2 pandemic has majorly affected medical activity around the world. We sought to measure the impact of the COVID-19 pandemic on gastrointestinal (GI) endoscopy activity in France. METHODS: We performed a web-based survey, including 35 questions on the responders and their endoscopic practice, from 23 March to 27 March 2020, sent to the 3300 French gastroenterologists practicing endoscopy. RESULTS: 694 GI endoscopists (21 %) provided analyzable data; of these, 29.4 % (204/694) were involved in the management of COVID-19 patients outside the endoscopy department. During the study period, 98.7 % (685/694) of endoscopists had had to cancel procedures. There were 89 gastroenterologists (12.8 %) who reported symptoms compatible with COVID-19 infection, and a positive PCR test was recorded in 12/197 (6.1 %) vs. 3/497 (0.6 %) endoscopists in the high vs. low prevalence areas, respectively (P < 0.001). CONCLUSIONS: The COVID-19 pandemic led to a major reduction in the volume of GI endoscopies performed in France in March 2020. The prolonged limited access to GI endoscopy could lead to a delay in the management of patients with GI cancers.

RESUMO

BACKGROUND AND AIMS: The aim of this study was to determine the mortality and re-bleeding rates, and the risk factors involved, in a cohort of patients with previous diverticular bleeding (DB). METHODS: In 2007, data on 2462 patients with lower gastrointestinal (GI) bleeding were collected prospectively at several French hospitals. We studied the follow-up of patients with DB retrospectively. The following data were collected: age, mortality rates and re-bleeding rates, drug intake, surgery and comorbidities. RESULTS: Data on 365 patients, including 181 women (mean age 83.6 ± 9.8 years) were available. The median follow-up time was 3.9 years (IQR 25-75: 1.7-5.4). Of these, 148 patients died (40.5%). Among the 70 patients (19.2%) who had at least one re-bleeding episode, nine died and three underwent surgical procedures. Anticoagulation and antiplatelet therapy was discontinued in 70 cases (19.2%). The independent risk factors contributing to mortality were age > 80 years (HR = 3.18 (2.1-4.9); p < 0.001) and a Charlson comorbidity score > 2 (1.91 (1.31-2.79); p = 0.003). Discontinuation of therapy was not significantly associated with a risk of death due to cardiovascular events. No risk factors responsible for re-bleeding were identified, such as antiplatelet and anticoagulant therapy in particular. CONCLUSIONS: In this cohort, the rates of mortality and DB re-bleeding after a median follow-up time of 3.9 years were 19.2% and 40.5%, respectively. The majority of the deaths recorded were not due to re-bleeding.

RESUMO

INTRODUCTION: Colonoscopy can prevent deaths due to colorectal cancer (CRC) through early diagnosis or resection of colonic adenomas. We conducted a prospective, nationwide study on colonoscopy practice in France. METHODS: An online questionnaire was administered to 2,600 French gastroenterologists. Data from all consecutive colonoscopies performed during one week were collected. A statistical extrapolation of the results to a whole year was performed, and factors potentially associated with the adenoma detection rate (ADR) or the diagnosis of polyps or cancer were assessed. RESULTS: A total of 342 gastroenterologists, representative of the overall population of French gastroenterologists, provided data on 3,266 colonoscopies, corresponding to 1,200,529 (95% CI: 1,125,936-1,275,122) procedures for the year 2011. The indication for colonoscopy was CRC screening and digestive symptoms in 49.6% and 38.9% of cases, respectively. Polypectomy was performed in 35.5% of cases. The ADR and prevalence of CRC were 17.7% and 2.9%, respectively. The main factors associated with a high ADR were male gender (p=0.0001), age over 50 (p=0.0001), personal or family history of CRC or colorectal polyps (p<0.0001 and p<0.0001, respectively), and positive fecal occult blood test (p=0.0005). The prevalence of CRC was three times higher in patients with their first colonoscopy (4.2% vs. 1.4%; p<0.0001). CONCLUSIONS: For the first time in France, we report nationwide prospective data on colonoscopy practice, including histological results. We found an average ADR of 17.7%, and observed reduced CRC incidence in patients with previous colonoscopy.

RESUMO

Gut-associated lymphoid tissue is a huge reservoir for HIV-1. Developing new strategies to target "residual" HIV-1 in patients on effective therapy brings the need for an evaluation of tissue reservoirs in the clinic. We measured cell-associated HIV-1 RNA and DNA in blood and rectal biopsies from 23 patients, including 14 with undetectable viremia on HAART, by using an adaptation of commercially available tests. Rectal cell HIV-1 RNA was detected in all viremic patients, with median levels of 4.90 log(10) copies/million CD4. Although plasma viremia was found at a median of 3 copies/mL in "aviremic" patients, rectal cell HIV-1 RNA was detected in 28.5% with median levels of 5.17 log(10) copies/million CD4. Consequently, we propose to use this marker in future clinical trials targeting "residual" HIV-1 in patients with viremia below the detection limit.

RESUMO

BACKGROUND & AIMS: Upper-gastrointestinal bleeding (UGIB) in the elderly is associated with high morbidity and mortality. The aims of this study were to determine the prognostic factors of UGIB in a large cohort of elders. METHODS: From March 2005 to February 2006, we conducted a prospective multicenter study in 53 French hospitals that consecutively enrolled 3287 patients for UGIB. A total of 1041 patients (47.8% women) were older than 74 years. Their epidemiologic characteristics and prognosis were compared with the 2246 younger patients (26.8% women). RESULTS: Elders more frequently took drugs causing UGIB: 65% versus 32% for younger patients (P < 10(-6)). Peptic ulcers, erosive gastritis, and esophagitis accounted for 63.6% of UGIB causes in elders versus 39.7% in younger patients (P < 10(-4)). Conversely, esogastric varices and gastropathy were responsible for 11% of UGIB in elders versus 44% in younger patients (P < 10(-6)). The rebleeding rate, morbidity, and in-hospital mortality were not statistically different between elders and younger patients: 11.8% versus 9.7% (P = .07), 22.6% versus 21.6% (P = .5), and 8.9% versus 8.2% (P = .5), respectively. Transfusion requirements, need for surgery, and length of stay were significantly different between elders and younger patients: 73% versus 57.5% (P < 10(-6)), 4% versus 2.5% (P < .02), 10.6 +/- 15.6 versus 8.5 +/- 12.4 days (P < 10(-6)), respectively. Whatever the etiology (peptic lesions or portal hypertension) in-hospital mortality was the same: 6.5% versus 7.3% and 10.9% versus 11.3%, respectively. CONCLUSIONS: Elders can do as well as younger patients with acute UGIB. Although the reasons are not completely clear, they may be related to differences in treatment.

RESUMO

Tuberculosis of the pancreas is unusual and often secondary to generalized tuberculosis. In most cases clinical presentation is obstructive jaundice due to pancreatic mass lesion. Although diagnosis is usually obtained after resection of the mass lesion, endoscopic procedures might avoid non-necessary surgical procedure. We report a clinical case of pancreatic tuberculosis diagnosed by endoscopic ultrasound guided fine needle aspiration biopsy and treated by biliary stenting.
